S3533 Series Spectrum Analyzer

Saluki S3533 series spectrum analyzer is a wide-band, high-performance analyzer with a frequency measurement range of 5kHz-8GHz/18GHz. Highly integrated RF front-end and full digital IF technology ensure its excellent performance and stable performance. The maximum real-time bandwidth of 40MHz meets the test of common radio signals such as mobile communication, TV and WiFi, and the 145MHz analog IF output provides users with a variety of test options. It has a variety of intelligent measurement functions such as spectrum analysis, network measurement, field strength measurement, channel scanning, third-order intermodulation, harmonic distortion, carrier-to-noise ratio and Pass-Fail.

S3533 series spectrum analyzer adopts all-aluminum metal structure chassis, 8.4-inch LED-backlit high-brightness standard display screen, and has good environmental adaptability. It can be widely used in aerospace, microwave communication, satellite navigation, radar detection, electronic detection and countermeasures, precision guidance and other fields.
